DRYING-OVEN.

Speccaton'of Letters Patent.

Applicationmed Anglia 1o, 1906. serial No. 329,988.

citizen of the United States, residing at` the city of Philadelphia, inthe county of Phi ladelphia and State of Pennsylvania, have 1nvented acertain new and useful Drying- Oven, of which the following is aspecification.

One object of the present invention is to provide an eiicient andconvenient oven for baking a finish on tools and the like.

Another object of the invention is to provide an oven and itsaccessories by means of which a great number of tools can be treated ina comparatively short time and even by unskilled labor. y Y

T o these and other ends hereinafter set forth the invention, statedingeneral terms, comprises the improvements to be presently described andI'inally claimed.`

The nature, characteristic features and scope of my invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which Figure1, is a perspective view illustrating y an oven embodying features ofthe invention and showing some of the parts removed. Fig. 2, is asimilar view illustrating parts of the apparatus shown in Fig. 1. Fig.3, is a sectional view illustrating a detail of con-` struction. Fig. 4,is a view illustrating another detail of construction, and Fig. 5, is aview illustrating one of the end frames of the oven. f

In the drawings l and 2, are a pair of ovens arranged side by side andeach is open at both ends and the open ends are tted with doors 3. Thereis a lengthwise ranging slot or opening 4, through the top wall of eachoven, and each oven ris tted with a heater 5, shown as consisting of agas burner arranged lengthwise along the floor of the oven.

6, indicates valved gas fittings for supply-u ing the heaters or burners5.

Arranged above the oven and parallel with the slots 4, are tracks 7 and8, which extend beyond the ends of the oven. 9, are carriages adaptedtothese tracks and suspended from them are carriers 10, 10a, 11 and 11a.Each carrier consists of a plate having at its top rods 12, which areconnected with the respective carriers by turn buckles so that thecarriers may be turned around while they are `suspended from thecarriages.

13, are pins which projectfrom the faces of the plates that constitutethe carriers. As shown these pins project through the carriers andareprovided on one side with a head 14, and on the other side with a nut15.

16, are coverV plates adapted to be detachably laid over the slots 4,and they are marginally notched for the accommodation of the rods 12.The oven consists of two end .frames connected together by metal insideand outside sheets which constitute the top, bottom and side walls ofthe ovens, and each frame consists of two generally rectangular frames17, slotted as at 18, and secured together along their meeting edges asat 19. The space between the inner and outer sheets is lled withasbestos between the frames 17.

20, are shields arranged above the burners 5.

In use one of thecarriers is placed in each of the two ovens and theother two carriers are outside of the ovens. Upon the pins of thecarriers which are in the ovens are suspended tools, the finish uponwhich is being baked and tools which are to be baked are being hung uponthe pins of one of the other carriers and finished tools are being takenoff of the other carrier. For this purpose the carriers may be turnedabout their swivels so that the operator may have access to the pins oneach of their faces. The operator may rst put upon the proper carrierthe tools which are to be baked and then remove those which have beenbaked from the other carrier, and this may be done while two of thecarriers arein the oven so as to have the tools which `they carry baked.When the carriersare to be moved, the plates 16, are removed and theseplates are applied so as to confine the heat during the baking operationjust as the doors 3, are closed during the baking operation andareopened to permit of the movement of the carriers. In this way theoperator may hang tools upon one of the carriers, remove tools from theother of the carriers while tools are baking at different stages ofcompletion on the other two carriers and by repeating these operationswith the `various carriers in rotation practically' none of theattendants time is ost.

I claim:

1. drying apparatus consisting of two ovens arranged side by side andrespectively The combination o't` an oven provided at provided at their'tops with slots and at their l its ends with doors and at. its top witha slot,

ends with doors7 carriers provided with facial pins, and arranged toenter and pass through the oven space, tracks having movable carriagesand arranged above the slots, connections between the carriages and theslots, and heating means within the ovens, substantially as described.

Q. rPhe combination of an oven containing heat-ing means and provided atits ends with doors and at its top with a slot, a track having a movablecarriage and alined Wit-h the slot, a tool carrier adapted to bereceived by the oven, suspension devices interposed between the carrierand the carriage, and a cover plate adapted to close the slot andnotched for the accommodation of the suspension means, substantially asdescribed.

a heater arranged near the Hoor ot the oven iii aliiieinent with theslot, a shield over the heater, a tool. carrier, a track having amovable carriage and alined with the slot, and

l means for suspending the tool carrier from carriers which areaccommodated by the` the carriage, substantially as described. 4E. Thecombination of a track provided with a movable carriage, a platesuspended from the carriage, pins penetrating the plate and providedwith heads and with threaded portions, and nuts engaging the threadedportions, substantially as described.
